Definitions

  • the invention relates to a plug connection which comprises a connector and an associated connector holder and is fastened in a front panel, and to a securing element that is suitable for it.
  • connectors are known in telecommunications and data technology. Examples are optical waveguide connectors, copper cable connectors or coaxial connectors for which associated matching connector holders respectively exist.
  • mini-duplex connectors where the connector comprises two glass fibers
  • M-RJ mini-duplex connectors
  • the mini-duplex connector and the MU connector have a push-pull lock, for example. All of these locking mechanisms protect the connector, to a greater or lesser extent, against inadvertently being removed. However, it is always possible to deliberately remove the connector. This constitutes a problem, however, in environments in which access can be controlled to only a limited extent.
  • the invention is based on the technical problem of providing a plug connection and a securing element that is suitable for it, which connection is used to more reliably prevent a connector from being removed and can be used to remove the connector in a manner that does not go unnoticed.
  • a securing element is used to secure the connector against being pulled out when inserted in the connector holder, with the securing element having at least one latching element and at least one cover part, with the latching element being used to connect the securing element to the connector holder and/or to the front panel in a captive manner, and with the cover part of the securing element covering a grip region of the connector and/or clamping the cable behind the grip region.
  • the securing element being connected to the front panel and/or to the connector holder in a captive manner, the securing element has to be destroyed in order to be removed. This in turn makes it possible to visually check, in a rapid and simple manner, whether someone has tampered with the connector in an unauthorized manner.
  • the basic principle of the securing element is that, if the grip region of most connectors is not accessible, it cannot be pulled. This applies equally to push-pull, bayonet, screw and latching connections.
  • the cable of the connector can be clamped behind the grip region. This results in the connector being fixed, at the front, by the latching element of the securing element and, at the back, by the clamping.
  • This variant is preferably used in connectors which could otherwise also be removed from the connector holder by pulling on the cable.
  • One advantage over conceivable key-operated locks is the simple and cost-effective implementation. Appropriate color markings also make it possible to sell the same securing elements to different customers, with the different colors making it possible to restrict misuse as a result of unauthorized passing on to third parties.
  • the securing element has a cutout, so that the securing element can be pushed onto the connector that has been inserted. Subsequent securing can thus be carried out without having to pull the connector.
  • the connector is in the form of an optical waveguide connector and the connector holder is in the form of a coupling or adapter, with a coupling being formed for the purpose of accommodating identical connectors, and an adapter being formed for the purpose of accommodating two connectors of different types.
  • the coupling is also even referred to as an adapter and the adapters are referred to as hybrid adapters.
  • the coupling or the adapter is fastened in the front panel using a front clip.
  • the front clip can be used to unlock the coupling or the adapter from the front side.
  • the front clip is preferably in two parts.
  • WO 02/27373 A1 As regards one preferred refinement of the front clip, reference is made to WO 02/27373 A1, to whose disclosure reference is hereby expressly made.
  • the latching element for the securing element is then latched into an opening in the front clip, with an additional blocking element for the securing element preventing the front clip from being removed.
  • the connector is in the form of an SC or MU connector having a push-pull lock.
  • the connector holder is in the form of a coupling or an adapter onto which a laser shutter (which can be retrofitted) is plugged, with the cover part completely covering the grip region of the connector in the longitudinal direction.
  • the securing element is preferably dimensioned in such a manner that, even when the laser shutter is used, this ensures that the grip region is completely covered.
  • FIG. 1 shows a plug connection of an SC connector having a coupling
  • FIG. 2 shows a perspective illustration of a securing element.
  • FIG. 1 shows a perspective illustration of a plug connection 1 having a coupling 2 .
  • the coupling 2 On the upper and lower faces, the coupling 2 has a respective flange 3 , 4 , by means of which the coupling 2 strikes against a front panel (not illustrated).
  • the coupling 2 In order to fasten the coupling to, and remove it from, the front panel, the coupling 2 has a two-part front clip 5 , 6 .
  • This front clip 5 , 6 is designed in such a manner that it uses latching hooks 7 to hook in behind the front panel and thus fasten the coupling. Pressing the areas 8 (which are on the upper and lower faces of the coupling 2 ) together unlocks the front clip 5 , 6 and thus the associated coupling 2 .
  • Attachments 11 comprising a laser shutter are also latched onto the front sides 9 , 10 of the coupling 2 .
  • the attachments 11 can thus be used to subsequently form a coupling 2 having a laser shutter in a simple manner.
  • a first SC connector 12 is inserted from the rear side of the coupling 2 .
  • the SC connector 12 comprises a grip region 13 , kink protection 14 and the glass fiber cable 15 .
  • the connector In order to pull the SC connector 12 , the connector must be held at the grip region 13 , that is to say the SC connector 12 cannot be removed by merely pulling on the kink protection 14 or on the glass fiber cable 15 .
  • the SC connector 12 is usually gripped and pulled on the grooved upper face 16 and lower face.
  • the securing element 20 has a planar rectangular upper face 21 and lower face 22 .
  • a cuboidal blocking element 23 on which a latching element 24 is located, is arranged on the upper face 21 .
  • the upper and lower faces 21 , 22 are connected to one another via a side wall 25 , whereas the other side has a cutout 29 .
  • the end face 26 (which is opposite the latching element 24 ) of the securing element 20 also has thickened regions 27 , so that a stop edge 28 is formed at the end of the thickened regions 27 .
  • the latching element 24 latches into an opening in the front clip 5 , with the blocking element 23 preventing the area 8 from being pressed down.
  • the upper face 21 and lower face 22 of the securing element 20 completely cover the grooved upper face 16 and lower face.
  • the side wall 25 also covers the protruding part of one side surface of the SC connector 12 .
  • the SC connector 12 can no longer be pulled without destroying the securing element 20 .
  • the latter must then be pulled with great force until the latching element 24 shears off at the front clip 5 .
  • the securing element 20 (which is preferably integral) is preferably made of plastic.
  • the upper face 21 , lower face 22 and side wall 25 form the cover part of the securing element 20 .
